Case ReportsDiscrepant opacification of the internal jugular veins: indicator of innominate vein occlusion on computed tomography of the neck.
Discrepant enhancement of an internal jugular vein on computed tomography during intravenous infusion of contrast material via an upper extremity vein constitutes an abnormal finding. We demonstrate that the greater degree of opacification of the internal jugular vein on the affected side is due to reversal of flow on that side and is indicative of occlusion of a major venous pathway proximally.

Case ReportsTracheal and bronchial stenosis associated with mediastinal adenopathy in Wegener granulomatosis: CT findings.
The computed tomographic findings of mediastinal adenopathy and tracheal and bronchial stenosis associated with Wegener granulomatosis are reported in a young patient whose disease appeared limited to the airways and sinuses.

Case ReportsPneumatosis intestinalis: role of computed tomography in diagnosis and management.
Four patients with pneumatosis intestinalis (PI) demonstrated by computed tomography are presented. Computed tomography delineated the location and extent of PI more accurately than plain abdominal radiographs and demonstrated any coexisting abdominal pathology. ⋯ In one patient PI would have been overlooked entirely using only conventional abdominal window settings. This technical observation could have potential clinical significance in the investigation of patients with suspected intestinal ischemia or gangrene where the appearance of intramural air is an ominous prognostic sign.

Four cases of pneumatosis intestinalis detected by computed tomography (CT) are described. Plain abdominal films obtained on the same day as CT failed to show pneumatosis in three of the four cases. ⋯ Evidence of pneumatosis should be carefully looked for in patients with acute abdominal pain referred for CT examination. Computed tomography may be a useful modality for the early diagnosis of bowel ischemia when plain abdominal films are noncontributory.
